A 101-year-old man in Britain has been convicted of sexual offences against children, becoming country’s oldest prison inmate.

A jury on Friday found Ralph Clarke guilty of 21 counts of indecency and indecent assault on two girls in the 1970s and ’80s. The former truck driver had admitted nine other charges against a boy.

Clarke was taken from Birmingham Crown Court in central England to prison to await sentencing on Monday. He was handed a 13-year prison sentence.

“You present as a fragile old man, however, what was plain to see was that, despite your guilty pleas, you have no remorse whatsoever,” Judge Richard Bond said during the sentencing on Monday, according to the Guardian.

Bond also said it would be “amazing” if Clarke lived long enough to be released.

Emma Fennon, a detective with West Midlands Police, said some might question prosecuting a 101-year-old. But she said “those he assaulted had to live with the suffering he inflicted on them for decades.” With files from the National Post
